The X-Files S04E22

Plot: Mulder and Scully investigate a series of deaths after reports that people are seeing the victims' ghosts just before they die. All of the victims were young women and in the most recent case, a bowling alley owner saw the victims spirit floating above the pin sorting machine at the end of one of the alleys. When they examine the bowling alley, they find the message 'she is me' on the floor. Harold Spuller works at the bowling alley and is slightly autistic. He lives in an institutional setting and to the local police, he is the prime suspect.
